The anti-skid devices now commonly used is the conventional tire-chain which com prises parallel chains with transverse spans that envelop" the circumferential surface of the tire; "Among the disadvantages; of this tire chain, are 'sagging'of the chain and the "danger of the tire chain becoming caught" in the brake-drum or on the axle with the possible breaking. of either, and-these disadvantages are avoided by myimproved anti-' skid device. 1 An object of my in'vention is to provide an anti-skid device'which combines the feature of a chain anti-skid surface and a'chain spreader. I I

Another object of my invention is to provide ananti-skid-device which is easily-applied and wherein the number of chain spans may be varied atwillf 'A- further object of my invention is to provide an anti-skid device simple in struc ture and reliable in operation wherein the internal structure to which the chain spans are secured may remain on the wheel all season long.

whereinv i i Figurel is aside elevational viewof the upper portion of an automobile wheel show- I v by 11163.118 of the ing my anti-skid device in place F igure 2 is a vertical cross-sectional view. Figure 3 is a view in perspective of the clampingmember which is positioned along the inner face of the Wheel felly andto which the chain spans are secured' Referring to Figure 1 of the drawing, the conventional artillery type of automobile wheel is shownwith hub A, spokes B, rim

The anti-skid chain spans 1 are transversely disposed in spaced relation on the tire tread and are secured to the arms 2, 3 of the clamping member 4:. The clamping member (as shown in Fig. 3) comprises a pressedsteel base plate 5 with halved ends, 6, 7 the A" still further object of my invention is illustrated the: drawings protruding portions 8, 9, of the basev plate being rolled to form loops. The arms 2, 3, each have'ahole at one end of a diameter corresponding to the loops 0n the base plate and the arms are. held in hinged relation j with the base plate by means of the bolt 10 which is provided with a wing nut 11 to allow of adjustment of the arms and their subsequent tightening into rigid position. By this adjustability feature, it will be appreciated that the clamping arms may be accommodated to'varying sizes of rims. Thelength offthe arms may be varied but in 110 case should'the length be such as to' interfere with the side walls of the tire shoe; The outer ends of the arms 2, 3, are each provided with aswivel hook 12. The hook 12 is preferably of such a type that itmay beop'erated by hand and at the sametime provide the secure holding grip that is necessary: As shown, it is ahook having a spring actuated tongue 13 which is pressed inwardly to insert the end link of the chain span and the latter cannot be released save by pressing inwardly the 'spring-tongue. In this way it is possible for a person to easily apply the chain spans as well'as to replace broken ones. This fastening means is suggestive and it is to be understood that other suitablefastening meansmay be used.

The clamping members are held in posi tion along the inner face of the-wheel felly by the mechanism now to be described. On the inner face of each base plate 5, a thread ed socket 14 is provided which receives the The inner threaded end 17 is screwed into one end of the turnbuckle 18. The angle bend 19 serves a purpose to be hereinafter stated; Another rod 20 is screwed into the other'end of the turnbuckle at its outer end 21 and the inner end 22 is received into sockets 23 which are disposed along the circumferential surface of the collar member 24. The number of the sockets may be varied, but it is recommended that a large number be provided inorder that-the use of varyingnumbers of turnbuckle arms may be made possible. By reason of the oflset af forded by the angle rod 16 the collar member does not touch the hub or spokes. The collar 24 is centered byreason of the opposing compressive forces exerted by the aligned turnbuckle arms on each side of the collar member. V

The manner and use of the improved anti skid device just described is 5 follows. The turnbuckle mechainsn'i is shortened and the claniipiun' arms are loosened. Any two dia- 1netrically opposed base plates are tightened into engagement with the inner face of the rim or telloe, care being taken that the collar member is centered at the same time. Then two other diametrically opposed base-plates are pressed against the rim by movement of the turnbuckle on the arms and it is sue gested that the arms at right-angles to the first arms lengthened should be selected. Then all the arms are lengthened and the base plates at their ends pressed against the rim, the collar member should be concentric with the Wheel. The clamping arms are raised into contacting position with the rim and then are tightened, The chain spans are next aflixed tothe swivel hooks provided on the clamping arms for this purpose and tbeantiskid device is ready for use. It will. be seen that with this organization no separate tire chain spreader is necessary nor is there any circumferential chains to sag loose and become caught on the brake drum or on the axle.

Innood Weather when the cliains are not needed, it is not necessary to dismount the internal structure. All that is necessary is to remove the chain spans. the internal structure consisting; of the clamping members. rods turnbuckle and collars remaining on the wheel all season long it desired. The nnn'iberof chain spans used may be varied at will as well as the number of turnbuckle arms. The facility with which the chains are added, removed or changed is a highly :ulvantageous feature o'l'" my proposed improvemcnt.

The material of which the parts may be made is a emitter of discretion although it is suggested that nickle plated parts would prove ornamental as Well as durable: how ever. itshonld be understood that l' comtemplate the use of any suitable material.

All that has been said above in the description of my preferred. en'ibodiment is uttered by way of illustration and not limitation. I. do not wish to be limited to the exact structure of the preferred embodiment shown and described, or to any particular material used in the construction of parts, or to the design of parts. but desire protection as against any. variations in structure \vliichutilize the principle of my invention andfall Within the par-view of my invention and are Within the spirit and scope of the :t'ollowing claims.

The invention havii'ig been set forth, what I claim as new and useful is as follows:

1. In an anti-skid device for automobile wheels or the like, means for securing anti skid members in operative position on a tire, said means con'iprising a plate member adapted to be disposed on theinner face of the Wheel telly, said plate member having ear portions oilset from the ends thereof, arm members bingedly secured to said oll'set car portions, said arm IIlOmbGTS being provided at their free ends. with securing means tor the reception of a detachable anti-skid member.

2. An anti-skid device for automobile wheels or thelikc comprising in combination, spaced plate members transversely disposed along the inner face of the wheel telly, means on. each side of: said plate members adapted for holding. anti-skid; means, and

radially extensible means for pressing said plate members against the Wheel telly. said radially extensible means con'iprising a series of rods. secured to said plate members, a centrally disposed collar member, a second series of rods attached to the exterior surface of said collar member, said second series of rods being fadially complen'ientary to the first mentioned series. and turnlmckle means applied to the opposing threaded ends of con'iplementary rods.

3. An anti-skid device tor automobile Wheels or the like com iirisingvin combination. spaced. plate members transversely disposed along the inner face of: the wheel. telly, means on each side of said plate members adapted for holding anti-skid means. radially extensible means or pressing said blatc members against the wheel "telly, said radi ally extensible ll'lGilDS comprising: a series oi rods secured to said plate memltiers. a centrally disposed collar member, a second series of rods attached to the exterior surface of said collar member, said second series of" rods being; radially complementary to the first mentioned series, and turnbuckle means applied to the opposingtln'eadedends of said complementary rods, said first mentioned series of rods having an offset portion.
